Kono Naka ni Hitori, Imouto ga Iru! Anime Announced5

According to the official website of Media Factory, light novel series Kono Naka ni Hitori, Imouto ga Iru! (この中に1人、妹がいる！, lit. One of Them Is My Younger Sister!) was green-lit for Anime adaptation. Written by Hajime Taguchi (田口 一) and illustrated by CUTEG, the series revolves around the protagonist Shougo who was asked to search for a female mate at school in order to inherit the family business. But instead of looking for a mate, he learned that his younger sister is among one of the girls. Sounds like something super Harem and super unhealthy with a plot of wealthy male turning a school into his Harem that common Galgame would love to offer. However, with a media of light novel, the series could possibly  stand out from the crowed.

Summary: The story centers around Shougo Mikadono, the son of an industrial magnate named Kumagorou Mikadono who passed away. As a final wish, Kumagorou gave Shougo a condition before Shougo can inherit the family legacy — find a female mate at school. Shougo transfers into a school to fulfill that condition. However, he learns that he has a younger sister who was separated at birth. He does not know what his long-lost sister looks like, but she happens to be one of the students at his new school.
